In the circuit diagram, the current through the Zener diode is

A) 10 mA                  

B) 3.33 mA

C) 6.67 mA                               

D) 0 mA

Correct Answer: B

Solution :

  The voltage drop across \[\tan \theta \le 3{{\mu }_{s}}\]is \[\tan \theta <3{{\mu }_{s}}\] The current through \[{{R}^{1/2}}\] is \[{{R}^{3/2}}\] \[{{R}^{-1/2}}\] The voltage drop across \[{{R}^{0}}\] is \[\sqrt{2}.\] The current through \[h:R\]is \[R:2h\] The current through Zener diode is \[2h:R\]
